Structural chemistry of organotin carboxylates

摘要: New diorganotin(IV) complexes of the general formula [R2Sn(A)2] and {[R2Sn(A)]2O}2 (where A is anion derived from N-phthaloyl derivative dl-valine R  Me, nBu nOct) have been prepared characterized by spectroscopic methods in case {[Me2Sn(A)]2O}2 compound, X-ray crystallographic methods. The Sn atoms are six-coordinate examples dicarboxylato tetraorganodistannoxanes. crystal structure shows both endocyclic exocyclic to be five-coordinate, trigonal bipyramidal. Several weak intramolecular contacts noted with most noteworthy being a contact 3.15(1) between imido CO atom atom.
